INFOID:0000000003332619
AFTER A COLLISION
WARNING:
Inspect all seat belt assemblies including retractors and attached hardware after any collision.
NISSAN/INFINITI recommends that all seat belt assemblies in use during a collision be replaced
unless the collision was minor and the belts show no damage and continue to operate properly. Fail-
ure to do so could result in serious personal injury in an accident. Seat belt assemblies not in use dur-
ing a collision should also be replaced if either damage or improper operation is noted. Seat belt pre-
tensioners should be replaced even if the seat belts are not in use during a frontal collision in which
the air bags were deployed.
Replace any seat belt assembly (including anchor bolts) if:
• The seat belt is in use at the time of a collision (except for minor collisions and the belts, retractors and buck-
les show no damage and continue to operate properly).
• The seat belt is damaged in an accident. (i.e. torn webbing, bent retractor or guide, etc.)
• The seat belt attaching point is damaged in an accident. Inspect the seat belt attaching area for damage or
distortion and repair if necessary before installing a new seat belt assembly.
• Anchor bolts are deformed or worn out.
PRELIMINARY CHECKS
1.
Check that the seat belt retractor, seat belt anchor and buckle bolts are tightend firmly.
2.
Repeat the step above if necessary to check the other seat belts.

REAR SEATBACK POWER RETURN SYSTEM
System Diagram
INFOID:0000000003432508
System Description
INFOID:0000000003418721
DESCRIPTION
• The rear seat back power return system is the system that enables the return operation of the left and right
rear seatbacks independently by pressing and holding the power return switch on the instrument panel or in
the luggage room.
• As for the safety mechanism, the reverse operation is performed if the power return switch is released during
the return operation. The anti-pitch function is installed so that the automatic reverse operation is performed
if the pinching of foreign materials between the left and right rear seatbacks is detected.
OPERATION DESCRIPTION
The rear seatback power return system consists of the sector gear that transmits the movement information of
rear seatback power return control unit, power return switch, power return motor, motor sensor, primary posi-
tion limit switch, return complete limit switch and power return motor.
Return Operation Starting Condition
The rear seat back return operation starts when all of the following conditions are satisfied.
• Vehicle speed 2 km/h (1 MPH) or less
• Return complete limit switch: ON
• The battery voltage is normal
• In the condition that the rear seatback is raised (return completion position), the sector gear is in the initial
position and the primary position limit switch and return complete limit switch are OFF.
• When manually operating the rear seatback to the fold-down position, the return complete limit switch turns
ON, and the rear seatback power return control unit judges that the rear seatback is tilted (return non-com-
pletion position).

REAR SEATBACK POWER RETURN SYSTEM
• When pressing the power return switch on the instrument panel or in the luggage room, the rear seatback
power return control unit detects the power return ON signal and supplies the power to the power return
motor. Then, the rear seatback power return control unit sounds the operation start buzzer.
• With the power supplied from the rear seat back power control unit, the power return motor rotates in the
return direction. The rear seatback starts the return operation via the sector gear.
• When the sector gear starts rotating in the return direction, the primary position limit switch turns ON. The
rear seatback power return control unit judges that the sector gear is in any position other than the initial
position.
• When the rear seatback moves to the return position, the return complete limit switch turns OFF. The rear
seatback power return control unit activates the return completion buzzer and stops the power return motor.
Then, the rear seatback power return control unit reverses the power return motor after 0.2 seconds so that
the sector gear returns to the initial position.
• When the sector gear returns to the initial position by reverse rotation of the power return motor, the primary
position limit switch turns OFF. The rear seatback power return control unit stops the reverse operation of
the power return motor. The return operation is completed.
• When releasing the power return switch during the return operation (both the primary position limit switch
and return complete limit switch are ON), the rear seatback power return control unit detects the power
switch OFF signal and returns the rear seatback to the fold-down position by the reverse rotation of the
power return motor. When pushing the switch again during the reverse operation, the return operation
restarts.
NOTE:
Disconnect the battery with the sector gear in any position other than the initial position (primary position limit
switch: ON). The sector gear is returned to the initial position when the battery is connected again.
ANTI-PINCH OPERATION
When the pinch between RH/LH rear seatbacks is detected during the return operation, the malfunction
detecting buzzer sounds and the rear seatback returns to the fold-down position.
• If there is a pinching of foreign materials between the left and right rear seatbacks during the return opera-
tion (both the primary position limit switch and return complete switch are ON), the voltage pulse of motor
sensor changes.
• When inputting the pinching signal from the motor sensor, the rear seatback power return control unit
sounds the malfunction detecting buzzer and stops the power return motor. Then, the rear seatback power
return control unit reverses the power return motor after 0.2 second so that the rear seatback returns to the
fold-down position.
SECTOR GEAR REVERSE STARTING CONDITION
If any of the following conditions are satisfied, the sector gear may be reversed.
• Rear seatback return is completed (return complete limit switch: OFF)
• Release the power return switch before completing the return
• Pinch detection
• Lock detection of power return motor
(Lock at normal rotation)
• The rear seatback return is not completed within 60 seconds
• Detect the battery voltage malfunction during the return operation
• Return to the normal condition after detecting the battery voltage malfunction during the return operation
• The primary position limit switch does not turn OFF
→
ON within the specified motor pulse number from
starting the return operation.
SECTOR GEAR REVERSE STOP CONDITION
If any of the following conditions are satisfied, the reverse operation stops.
• Sector gear initial position (primary position limit switch: OFF)
• Lock detection of power return motor (Lock during reverse operation)
• The sector gear initial position is not completed within 60 seconds
NOTE:
The battery voltage indicates the voltage between battery voltage (system) terminal 17 and GND (system) ter-
minal 32 of rear seatback power return control unit. It is normal when the voltage is 7.5
±
10% or more. If it is
less than the specified value, there is a malfunction.
POWER CONSUMPTION CONTROL SYSTEM
Rear seatback power return control unit incorporates a power consumption control function that reduces the
power consumption according to the vehicle status.

Low Power Consumption Mode
If all of the following conditions are satisfied for 30 seconds period of time, the system shifts to the low power
consumption mode.
• Power return switch is OFF
• Power return motor does not operate
• Vehicle speed 2 km/h (1 MPH) or less
If any of the following conditions are satisfied, the low power consumption mode is released.
• When the power return switch is pressed
• When the change occurs to the pulse of vehicle speed sensor
There are the following functions as the low power consumption mode.
• Turn the power supply of limit switch to OFF
• Turn the power supply of the motor sensor to OFF when the power return motor is not operated
